Positioned in Fischer's sport motorcycle lineup, the 2009 Fischer MRX SP pairs a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 77 HP (56.2 kW) at 9,400 rpm while maximum torque reaches 52 Nm (38.4 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 119 HP per liter and a 1,900 rpm working window between peak torque (7,500 rpm) and peak power (9,400 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the MRX SP measures 157.4 kg (347 lbs) dry, translating to a power-to-weight ratio of 0.49 HP/kg (2.04 kg per horsepower). Rider ergonomics and chassis geometry center around a 749 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,397 mm (55 in) wheelbase engineered for quick, flickable steering geometry. The 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
